Reading Parameters
Product Reference Guide 169
When one read per cycle is selected, the device decodes only one code during the ON period
and immediately turns the reader OFF. It is only possible to read another code when the
next ON time occurs.
In multiple reads per cycle, the ON period is extended so that the device can continue
decoding codes until an OFF event occurs. For software trigger mode, the
flash on period is
immediately reset after each read and therefore extended. If another code is decoded before
the reset
flash on period expires, it is again reset and the effect is that the device remains ON,
decoding codes until the flash on or timeout period expires.
The Safety Time parameter should be used in this case to avoid unwanted multiple reading
of the same code, see below.
Safety Time
Safety time prevents the device from immediately decoding the same code more than once.
Same code consecutive reading can be disabled requiring the reader to be removed from the
code (no decoding) for at least 400 ms, or a timeout can be set up to 9.9 seconds before the
decoder will accept the same code. Reading is immediate if the code changes.
The safety time parameter is not applicable when reading stacked codes or when setting one
read per cycle in hardware trigger operating mode, since these settings require voluntary
action by the user.
